A queen and her prints : a study in 3D modeling and printing for theatrical costumes
(2019-05-08) Lopez, Vanessa Jeanette; Glavan, James
3D printing is not new technology. In our current day, it offers us endless design opportunities and manufacturers of 3D printers have made them as user intuitive as possible. Yet even with the exponential growth in accessibility to the mainstream consumer market, 3D printers are still not commonly found in most costume shops around the nation. The exception being larger commercial shops with corresponding larger budgets. Upon having casual conversations with my peers in various costume shops, the common consensus is that the 3D workflow process appears to be overcomplicated, especially for us drapers who are not traditionally trained in vector and modeling software. For my MFA thesis, my objective was to obtain a better understanding of why costumers tend to stray away from 3D printing, and also as a costume technician and crafts artisan, I wanted to know what specific pros and cons 3D printing offered my current existing costume making workflow. I also wanted to understand how easily this technology could be incorporated into my already existing skill set considering I was a novice who had never encountered any sort of modeling software prior. To do this, I designed and built a stylized peacock inspired costume for the character ‘Titania’ from William Shakespeare’s A Midsummer Night’s Dream with the intention that her base garment would be constructed using traditional dressmaking techniques, and her jewelry, crown, and feathers would be fabricated digitally on a 3D printer. I wanted to ensure that this project was for the benefit of the everyday 3D workflow novice specializing in costuming, like myself, so a lot of choices in my project were dictated by ease of use and lower costs. This culminated in me sharing my research and final peacock costume at the annual United States Institute for Theatre Technology stage expo and conference to a room full of costume professionals and enthusiasts.
Communicating in Three Dimensions: Questions of Audience and Reuse in 3D Excavation Documentation Practice
(2019-08-18) Rabinowitz, Adam
After excavating the Praedia of Iulia Felix at Pompeii in 1755, architect Karl Weber published the building with an axionometric illustration that showed the remains in three-dimensional perspective. In doing so, Weber communicated additional information about the form of the building in a manner that was both visually accessible to a lay audience and sufficiently “scientific” for a scholarly one. By contrast, digital 3D documentation methods in current archaeological practice can reinforce a division between “scientific” models intended for internal consumption by the project that produces them, and external communication in the form of lower-quality online digital displays. Using recent fieldwork at the Greek colonial site of Histria in Romania as a case-study, this paper explores the space between high-resolution contextualized 3D documentation used only by an internal audience and down-scaled, decontextualized 3D content designed for public consumption. In particular, it explores whether measurable 3D models derived from photogrammetric capture are useful in communicating excavation results to non-specialists – and if so, in what ways. It presents several scenarios for the role of high-quality 3D documentation in both formal and informal scholarly communication and discusses the potential for the reuse of such documentation to answer new research questions.
Computing transformation in an irregular teeth set
(2011-12) Seshagiri, Naveen Krishnamoorthy; Crawford, Richard H.; Campbell, Matthew I.
The research evaluates the feasibility of assisting orthodontists to treat irregularities in teeth by computing the transformations to move each tooth to its ideal position. The intent is to help orthodontists craft a precise and specific treatment plan for each patient. Computation of the transformations is achieved through the use of a reverse engineering package, Geomagic Studio, and a three dimensional modeling program, Rhino3D. The inputs for finding the transformation are the patient's teeth mold and dental arch templates. A 3D laser scanner is used to form a point cloud data representation of the patient's teeth mold. Geomagic is used to construct a Non-Uniform Rational B-Spline surface for the mold. Rhino3D is used to manipulate this surface and compute the required transformations using the scripting platform, Rhinoscript, in Rhino3D. The steps in the process and the algorithms developed in Rhinoscript to compute the transformations are discussed. Three case studies are presented to demonstrate the process.
Efficient Three Dimensional Modelling of Additive Manufactured Textile Structures
(University of Texas at Austin, 2012) Bingham, G.A.
Textile structures realised by Additive Manufacturing (AM) techniques have received increasing attention during the previous decade. Due to their potential to significantly improve upon both the geometric complexity and functionality available from conventional fibre-based textiles, AM textiles present a serious opportunity to design and develop novel solutions for conventional and high-performance textile applications. AM textiles also provide the capability to produce net-shape textile artefacts and allow the development of personalised, high-performance textiles from a variety of materials currently being processed by AM technologies. While the motivation exists for the wider-scale adoption of these novel structures, practical access to an efficient three dimensional (3D) modelling strategy limits their applications. The research presented here discusses the issues surrounding the 3D modelling of complex AM textiles and discusses dedicated methodologies developed for the generation of their conformal data. The research culminates with a robust methodology for the generation of AM textile apparel data suitable for manufacture by AM techniques.
Touch-RE: A Touch-based Model Acquiring Method for Personal Manufacturing
(University of Texas at Austin, 2010) Jung, Jinho; Chen, Yong
Enabled by additive manufacturing technology, personal manufacturing, if realized, will give ordinary people control over their physical world by allowing them to personally program its construction. Currently several pioneering mass customization and personal fabrication applications have been developed for consumer products, gifts, toy, etc. However, one of the core challenges that are remained to be addressed for realizing personal manufacturing is the easiness of creating 3D models for additive manufacturing systems. Current developments in CAD software and reverse engineering are still lacking on the easiness of usage especially for normal users without much experience. In this paper, we present a touch-based 3D-shape acquiring method that is easy and intuitive to use. The key technical challenges on the related hardware and software development are discussed. A testbed system is presented and multiple examples are given to demonstrate its capability.
